Example 2:

Input:?sentence = "this problem is an easy problem", searchWord = "pro"Output:?2Explanation:?"pro" is prefix of "problem" which is the 2nd and the 6th word in the sentence, but we return 2 as it's the minimal index.

Example 3:

Input:?sentence = "i am tired", searchWord = "you"Output:?-1Explanation:?"you" is not a prefix of any word in the sentence.

?

Constraints:

• 1 <= sentence.length <= 100

• 1 <= searchWord.length <= 10

• sentence?consists of lowercase English letters and spaces.

• searchWord?consists of lowercase English letters.

Easy題目，先把sentence 根據(jù)空格分列，分成數(shù)組，

然后遍歷數(shù)組，

如果是prefix，則返回；

沒有就是-1；
